Finally got to where I wanted to be. After all the messing around I was doing, I simply tried using an em instead of px. Guess what, the result that I wanted.
I'm sure there will be some draw back to using em over px but at present it suits a little better. Try visiting
www.thehealthzone.co.uk and using ctrl and the mouse wheel to see how it all expands and compresses.
Cheers all!
